IMPROVEMENT IN STRAW-C UTTERS.

Specification forming part of Letters Patent No. 183,285, dated October17, I876; application filed January 29, 1876.

To all whom it may concern:

Be it known that I, JOHN Q. ORosBY, of Newark, in the county of Essexand State of New Jersey, have invented certain new and usefulImprovements in Straw or Feed Gutters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it pertains to make and usethe same, reference being bad to the accompanying drawing, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in straw-cutters; and has for itsobject to provide means whereby the knife may be readily adjusted to themouth-piece or cutter-frame, and whereby those parts liable to break orto be bent may readily be replaced at small cost.

It consists in aremovable hollow axial stud, in a detachable hub orbearing for the knifelever, and in other mechanism, as hereinafter fullyexplained.

In the drawings, Figure 1 is a front elevation of my device complete.Fig. 2 is a top edge view of Fig. 1; and Figs. 3, 4, 5, 6, 7, 8, and 9are detail views of the several parts.

a is the mouth-piece of the cutter, on which is formed the extension 00,to which the several parts hereinafter described are secured. a a aretwo clips or lugs attached to the extension a They have their innersides under beveled or grooved, so that the edges of the supplementalplate or are hereinafter described will slip therein, and be heldsecurely to the extension a b is the axial stud. It is made hollow, asshown at 12 and is held to the frame a by the retaining-screw 01,passing through the bore b and hole a in the extension a. It isconnected with the plate or are I), with which it forms a single pieceor casting, and may be readily removed when desired. The plate or are I)has its edges slightly beveled, so that it will slip into the undergrooves on the clips a by which it will be held firmly in place. It willbe seen that when the retaining-screw d is put through the stud b andhole a in the frame a, the plate or are I), with its stud b will be heldas securely in place as if it was a part of the said frame. 0 is the hubor bearing by which the knife-lever is connected with the axial stud bthereto, and forming a part thereof, is the plate c, which oscillates orturns with the hub, and which is made to extend out flush with y theouter edge of the plate b, on which it slides desired.- d is a washerplaced over the top of the stud b and hub 0 after the latter has beenplaced on said stud. e is the knife-lever, which is secured to the hubor bearing 0 by the screw or bolt 0. I

The knife-lever is provided with the extension 0 in the end of which isplaced the setscrew 6 by which the knife may be adjusted to themouth-piece. The screw 6 bears or abuts against the plate 0, and inadjusting the knife by turning the screw in or out the plate is notmoved, and by reason thereof no strain will be placed on the hub 0 noron the stud b. The plate 0 protects the screw from being worn away orbent, as would be the case did the end of said screw slide on astationary bearing.

It will be readily seen that should any injury be done to the stud 11 orto the hub 0 these parts could be replaced at small cost.

It will be further understood that the plate 11, carrying the stud bcould be secured to the extension a by means of screws or bolts passingthrough, the screw-heads being countersunk in the plate I), to permitthe free movement of the are or plate 0; but I prefer the constructionwith clips, as described.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

' l. The plate b, provided with the hollow axial stud b secured to theplate or frame a by the clips c and screw d, substantially as Attached2. The hub or bearing 0 provided with the dovetail groove 0 andoscillating plate or arc c, all constructed and operating substantiallyas and for the purpose set forth.

5. The combinationof the detachable hub and plate or are c with theremovable hollow axial stud b and plate I), substantially as shown.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.

JOHN Q. CROSBY. Witnesses:
